Btw this game is awesome those complaining probably don't understand or have a messed up computer or keyboard (like bedog). You should make more of these and make the game and minigames easier for people to understand and play.
I just beat the first level on medium difficulty with all archers just by shooting and taunting. I ended up with 2748 troops left and 58 morale. It went pretty well for not being able to use any melee troops.
